I looked for a different type of mounting on the DIN rail than is used in the official release of Voron parts - I was not at all satisfied with the type and design ☹
For the DIN Rail Bracket Mount you need M3x10 countersunk screws.
The author remixed this model.
DIN
Adjustment of the hole for M3 Heat Inserts up to 5.0mm, so that there is not a large excess of extruded plastic.
Source holder
Adjusted the height of the part so that it can be used in the construction of the Voron 2 printer.
For the Power Supply you need M4x12 screws.
